readings for the next 12 to 24 hours. These changes will require a 12  to 24 hour wait before 
obtaining reliable data. 

 

To achieve a true temperature reading, avoid mounting where direct sunlight can reach the 
outdoor temperature transmitter. It is  recommended to mount the outdoor temperature 
transmitter on a North-facing wall or in any well shaded area. The maximum transmitting range is 
330 feet (100 meters).  Obstacles such as walls, concrete, and large metal objects can reduce the 
range. 

 

Place both units in their desired location, and wait approximately 10 minutes before permanently 
mounting to ensure that there is proper reception.  The outdoor temperature transmitter is not 
waterproof and should not be placed anywhere it will become submerged in water or be directly in 
the rain. 

 

POSITIONING THE ATOMIC CLOCK: 

There are two possible ways to mount the atomic clock: 

 

use of the foldout table stands, or 

 wall 

mounting 

 
FOLDOUT TABLE STAND 

 

The foldout table stand legs are located on the backside, at the lower corners, just 
below the battery cover. The hinges are towards the edges of the  atomic clock, and 
the ends (with no hinge) need to be folded out towards the edge. Once the foldout 
table stands are extended, place the atomic clock in an appropriate location.
